See #131 for a chronicle of the "great snow" in 1982 (Houston). I think it lasted a day, but it was memorable.
I remember that day very well. I do not remember if it was a school day, but if it was school was cancelled. My friends and I were outside before 8 am having snowball fights. By 11 am the only snow that was not melted was on the cars or roofs. We collected some of the snow in bags and placed it in the freezer.
I remember it was a work day because I remember begging my husband to come home early. The freeways were a mess. It probably wasn't a school day (unless school was cancelled) because my youngest son would have been driving to Strake Jesuit College Prep, and I would have been frantic with worry. It was right at the end of Christmas vacation, on a Monday, or Tuesday. I know that I did not leave the house.
I remember that it cleared for a little while around noon (when the dog escaped) and then it started snowing again for the afternoon rush. The bridges all iced over, which is what made it so treacherous. The following day was fine.
